1 indicates the :main casing or housing of my waxing and polishing device. The side wall 1 ofthe housing is flared outward at 1, the. flared out portions being provided with a cut awayrecess Qextending from the point at which the flare commences to the forward extremityof the machine By this means an opening is formed which will permit the casing passing over the base bead ofv a skirt boardso thatthe waxing or polishing elementofthe machine may operate close up to the head as will hereinafter appear.

The side wall 1 of the housing is provided. in its front edge withan open. ended slot 3.

The opposite wall? is provided with a see-.-

tionary stud 4 secured to'the wall by screws 4* and on which is mountedan inner race 5 .of ahall bearing.

.6 1s the outer race of the bearing and? the balls. The outer race 6 is secured within a recess8'formed in thedriving pulley9.

By this means the driving pulley 9 is rot-at.-

ating motor of the machine and 11 the driving pulley secured to the motor shaft. 12 is 9 at its opposite end. Theinner face of the pulley 9 is convexed as indicated'at 9* and the convexed face is provided withacentral rectangular opening 9. The edges of the orifice 9 may he chamfered off for a purpose which will hereinafter appear. 7

13 is the centre cylindrical core of a waxing element provided at one end with a sta- 'tionary stud 13"; the edges of which are also chamfered off to permit of the easy insertion of the stud into the orifice 9. The opposite end of the cylindrical core 13 is provided with a cylindrical stud 14 provided with I a rectangular projection 14? extending outward therefrom and adapted to fit into the open ended slot: 3. ofthe casing.

The inner portion of the stud '14 is reduced as indicated at 14, such reduced portion be ing driveninto the inner race 15 of ahall bearing, the outer race 16 of the bearing bearm 19 fitsinto the recess 23 against the forr erated the stud 21 is forced longitudinally 'of the locking member 18 so as to carry the ing secured in the end of the cylindrical core 13.

17 are the balls of the bearing.

By this means the cylindrical core.13 is revolvably mounted within the casing and driven from the motor through pulleys 11 and 9 and belt 12.

In order to detachably lock the core in the machine I provide the following device. 18 is a slot formed in the side wall 1 of the machine provided at its forward end with a downwardly extending portion 18. 19 is a locking member, provided adjacent its lower end with a right angular arm 19 which is pivoted at 20 to the wall 1 of the machine. The slot 18 is concentric with the pin 20. The upper end of the'locking member 19 is provided with. a longitudinal slot 19. 21 is a button which bears against the outer face of the walll andis provided with a centralstud 22 whichextends'through the slots 18 and 19, the inner end of the studbeing suitably enlarged to preventiits'outward withdrawal.

The stud 14 is cut away around the rectan-I the slot 18 opposite to the inclined extension thereof. WVhen in this position the inner edge ofthe locking member 18. below the ward face ofthe stud 14*, the lower edge of the arm 19 fitting'intherecess' against the upper face of the stud. J I 7 After the locking member has been so opstem 22 of such stud longitudinally of the slot 19 intothe slot extension 18*, thereby preventing the inadvertant return movement of the locking member.

By this means it wil be seen that the stud 14* is securely locked within the slot 3 from outward movement.

25 is a cover formed of felt. The cover 25 is cylindrical and fits over the core 13. 26 is wrapper which is detachably secured at its ends to the core 13 in an overlapping position.

WVhen the element is'used as a waxing element the wrapper 26 is made of comparatively coarse fabric through which the Wax may penetrate. When'the wrapper is used as a polishing means is made of felt or other suitable material through which the wax will not percol'ate and which is soft so as tohave a polishing effect.

1 will now describe the means by which .the wrapper when either made of the coarse "snap ends 29*.

to the socl-cet members extending lnwardly fabric or of the felt may be detachably secured to the core. I

27 is a groove extending longitudinally 01' the core 13 from end to end. 28 is a plate which is arched transversely to correspond with the periphery of the core 13 and is countersunk in the surface of the core so as to extend over the groove 27. 28 are orifices' formed in the plate 28 at suitably spaced apart positions. 29 are cylindrical socketmembers extending out-ward around the orfices 28 and provided with spring 30 are cylindrical extensions of the plate 28 and areprovided at one side with. vertically slotted openings 3O from which extend guide walls 31 and 32. 33 and 34. are plates forming the ends of the groove 27. 35 and 36 are bearing blocks secured transversely within the groove 27 by screws 35* and 36a. 37 is a rod which is secured in the bearing blocks 35 and 36 by securing pins 37 V 38 is a rod which is 'slidably held within the bearing blocks 35 and 36 so as to move longitudinally. 39 are finger pieces which are pinned or otherwise suitably secured as indicated at .40 to the rod 38. 41 are hooked catches provided with inclined upper" ends 41*. The hooked catches 41 are providedv with'sleeves 41 which are'slidably held upon the rod 37 and are spring pressed against the finger pieces 39 by compression springs 42 bearing at heir outer ends against projections j The rod 38 extends at one end through an orifice 33 in. the plate 33 and is provided at its outer end with a thumb passed around the felt covering 25 in the direction of arrow, see Fig. 5. The oppositeend of the cover 25 is provided with a series of pin projections 46 adaptedto fit the socket projections 29 so as to extend therethrough into the extension 30.

Each pin 46 is provided with longitudinal slot 47 whichwhen the pin is inserted is opposite the interspace between the walls 31 and 32. The inner end of the pin 46 is pref-' erably rounded off and the slot 47 tapered for a purpose which will hereinafter appear.

The felt cover 25 is provided with orifices 25 through which. the socket members 29 extend. The wrapper 26 particularly when used for waxing is preferably applied to the element by first snapping the eyelets into engagement thenlayingthe wrapper on the floor in front of the element, then spreading the wax on-the upper face of the wrapper and then operating-the machine forward so asto rotate the elementfand wind the wrapperthereon the pins 46 then being inserted into the .socketsfor engagement. p V U The wrapper when passed around the waxing element retains the wax'between the Wrapper and the felt -covering25, theopposite end of the wrapper being then secured by, individually passing each of the pins 46 into their respective sockets 29. As each pin 46 is inserted it engages the inclined upper end 41* of thecorresponding catch 1-1, thereby forcing such catch longitudinally on the rod 37 against the pressure of the spring 42, the pin 46 then passing downward so that the hookend of the catch springs into engagement with the slot 47.

It will thus be seen'that each pin 46 is individually engaged so that the free end of the wrapper may be readily buttoned into position.

Thefupper end ofth'e catches 41 are also tapered laterally and the slots 47 as before stated are correspondingly tapered so as to permitof the ready entrance and centering of the hook end of the catch.

In order to limit the return movement of the rod 38 I'provided a pin projection at? extending therefrom to engage the bearing 35. t

From what hasbeen before set forth it will be readily understood that the hook catches 41 may be simultaneously released by pressing upon the thumb button 4 so as to operate the rod 38 longitudinally andthe catches as has been before set forth.

When it is desired to remove the coarse fabric wrapper so as to attach the polishing wrapper all itis necessary to dois to press upon the thumb piece 43, thereby relieving one end of the attached wrapper, unwrapping such wrapper and pulling the eyelets 45 out of engagement with-the spring ends 29 of the sockets 29 and then applying the felt wrapper which is simultaneously engaged in the spring sockets 29*, wrapped around the cylindrical felt wrapper and engaged by the buttoning action hereinbefore described in relat on to the coarse fabric wrapper.

When the felt wrapper is used the eyelets instead of being directly attached to the felt are preferably attached to a strip of fabric secured to the end edge of the felt and the corresponding pins 46 to a similar strip of fabric secured to the opposite end edge of the felt.

this means the increased thickness of material is compensated for at the overlapping ends of the wrappen If desired instead of using the polishing wrapper as above described a separate element may be employed consisting of a cylin drica-l brush provided with endprojections corresponding; to those employed .in connection; with the Waxing and polishing element above described;

.T'he waxing and polishing element may be I easily-removed by operating the thumb but ton 21 so as to removethe lockingarm 19 out of engagement with the stud 14*. The corresponding end of the element isthen swung outward so as to carry the stud 14* through actionagainstthe convexed. face of. the pulley 9 so that the outwardly swung end of the element will be carried'clear: of the wall 1 so that it canthen be moved longitudinally to carry the projection out ofthe orifice 9". The

brush may then be inserted by 'areverse op-' eration, that is, placing the brush in thedotted line position shown in -Figure 2 with one end in contact with the convexed face of the pill ley 9, then'swin-ging the brush inward so as to, carry the projection into the orifice 9 and permitting the opposite end of the brush to enter within'thewall 1 of the casing and the stud l l 'into engagement with theslot 3:

It might be pointed out that the cover 10 issuitably insulated from the'casing land a fibre or other insulating material may be inserted between the stud 4 and the pulley 9 asindicated at X and the stud la 'may be also'm'ade of fibre or other suitable insulatingmaterial. It will'thusbe seen that the whole'machine is thoroughly insulated and is'as noiseless .a'sitis possible tomake a machine o'fthis type. 1 r
